Patent ES-8204671-A1 (ES)
Title: Automatic speed control systems.
IPC: F02D41/14
Filed: 1981-08-07
Abstract: A vehicle speed control system is disclosed which is primarily intended for heavy vehicles and which is arranged to 'anticipate' an uphill section of road immediately following a downhill section, so as to prevent loss of momentum gained on the downhill section. A comparator compares an actual speed signal Vs with a driver-settable desired speed signal Vr and produces an error signal. A level changing circuit produces an output equal to Vr in normal circumstances, but which follows Vs when the vehicle accelerates downhill. This output is fed through a memory via a switch which is open when an acceleration-deceleration unit detects that the vehicle has reached the foot of the hill. This memory therefore stores a signal Vr' representing the speed at that time, and the comparator therefore increases the engine power when the vehicle speed has fallen below this augmented reference speed, instead of waiting for the speed to fall to the original reference. Another comparator detects when the vehicle speed on the uphill section has fallen to the original desired speed and closes the memory switch so that the reference reverts to Vr. Another unit closes the memory switch to ensure that the reference is brought back from Vr' to Vr if the vehicle speed increases (such as if the downhill section is followed by a level section of an uphill section).
Patent ES-8302375-A1 (ES)
Title: Battery charger.
IPC: H02J7/00
Filed: 1981-11-20
Abstract: A battery charger with an SCR providing high charging current to a battery until a predetermined high voltage level is sensed. When the voltage sensed reduces to a float voltage minimum level, a trickle charge current is supplied through another SCR until a float voltage maximum level is sensed, which suspends trickle charge current until the voltage again reduces to the float voltage minimum level. When a load reduces the battery voltage so that the sensed voltage is reduced to a predetermined low level below the float voltage minimum level, then the high charging current SCR is again gated on to charge the battery.

Title: Method and apparatus for the detection of reducing gases in a gaseous mixture.
IPC: G01N33/00
Filed: 1985-04-03
Abstract: Reducing gases can be detected in a gas mixture to be investigated, particularly in air, with high sensitivity and precision by means of a gas detector. The gas detector comprises a gas sensor which is arranged within a measuring chamber. The temperature of the gas sensor can be continuously increased according to a predetermined pattern from a starting value to an upper threshold value and can be subsequently decreased again to the starting value according to the same or according to a different pattern. There are provided at least two such heating cycles. Simultaneously therewith the gas mixture to be investigated, which is present in the measuring chamber, is periodically exchanged against a pure reference gas which is contained in a reference chamber. A selected property, such as the electrical conductivity of the gas sensor is thereby periodically changed. The temporal variation of this periodically varying electric conductivity can be detected in an evaluation circuit arrangement and/or evaluated for determining the concentration and/or the nature of the reducing gases which are present in the gas mixture to be investigated.

Patent ES-8703603-A1 (ES)
Title: Method and apparatus for implementing a thermodynamic cycle using a fluid of changing concentration.
IPC: F01K25/00
Filed: 1985-10-15
Abstract: A method and apparatus for implementing a thermodynamic cycle involves utilizing partial distillation of a multi-component working fluid stream. At least one main enriched solution is produced which is relatively enriched with respect to the lower boiling temperature component, together with at least one lean solution which is relatively impoverished with the respect of lower boiling temperature component. The main working fluid is expanded to a low pressure level to convert energy to a usable form. This spent low pressure level working fluid is condensed by dissolving with cooling in the lean solution to regenerate an initial working fluid for reuse. A portion of the impoverished fraction may be injected into the charged gaseous main working fluid in order to obtain added work and to increase system efficiency by decreasing the temperature of the output fluid flow when the fluid flow would otherwise have been superheated. A low pressure, low temperature expanded spent fluid may be distilled using low quality heat to create an enriched solution which has a significantly higher concentration of the lower boiling component. For this enriched solution, a reduced temperature and pressure is sufficient to enable distillation. The efficiency of the cycle may be enhanced by charging the spent fluid with the lower boiling temperature component prior to distillation. This may be accomplished by lowering the pressure of the impoverished fraction to separate an additional lower boiling temperature fraction.

Patent ES-8800709-A1 (ES)
Title: Process for regenerating coke-contaminated catalyst.
IPC: C10G47/00
Filed: 1986-04-24
Abstract: Particulate catalyst which has been used in a hydrocarbon conversion process such as catalytic reforming is regenerated in a moving bed regeneration zone (12). The catalyst being regenerated is passed into the top of the zone (12) and slowly moves downward as a dense bed (14, 19, 20) which is contacted successively with an oxygen-containing gas stream (31), a temperature-adjusting gas stream (30) and either a drying gas stream (37) or a chlorination gas stream (39) or both at different elevations within the regeneration zone (12). A key feature involves employing a portion of relatively hot combustion gas (26) withdrawn from one portion of the zone (12) as the temperature-adjusting gas stream (30) in a different portion of the zone after compression, with the remainder of the compressed combustion gas (27) being cooled (32) and recycled to the combustion zone as the gas stream (31). This eliminates the need to employ a heater to provide a suitable heating gas stream.
